(b) Insurance Against Loss or Damage. Lessee, at its own cost and expense, will maintain in effect with Approved Insurers "all-risk" ground and flight aircraft hull insurance (which shall include, but not be limited to, war risk and allied perils, hijacking, and coverage against strikes, riots, commotions or labor disturbances, malicious acts or acts of sabotage and unlawful seizure or wrongful exercise of control of the Aircraft in flight by a person on board such Aircraft acting without the consent of Lessee, and foreign object damage (defined as sudden and unexpected impact with a foreign object requiring immediate withdrawal of the Engine from service) to Engines) covering such Aircraft, and fire, transit and extended and "all-risk" coverage insurance with respect to Engines and Parts while not installed on such Aircraft or an aircraft, which in each case is at least as broad as coverage of the type usual and customary by U.S. airline standards for airline carriers operating other similar aircraft in similar operations and carried by Lessee on the other aircraft in Lessee's fleet. Such insurance shall be for an amount not less than the Casualty Value. Such insurance shall include provisions for deductibles in an amount of not more than Five Hundred Thousand Dollars (US$500,000.00). No deductible shall apply in the event of a Casualty Occurrence.
